Question: Power Search hangs when I try to crawl using my Regular Expression. What’s wrong?

Answer: It is possible to construct a Regular Expression that will never finish running. There is a good chance that you accidentally created a Regular Expression like this. The easiest way to diagnose this type of problem is to download a tool such as Expresso and test your Regular Expression on some sample input (such as the HTML from a webpage).
